Find the Thevenin equivalent voltage and current for the network shown in Figure 1-2 below if

Solution: As per Thevenin's theorem, the equivalent circuit at the given terminals will comprise of a voltage source in series with an equivalent impedance. The voltage of the voltage source and the equivalent impedance are to be determined as follows :

i) to determine the voltage of the voltage source, we open the terminals and determine the open circuit voltage across the terminals.

ii) to determine the equivalent impedance, we short the voltage sources and open the current sources in the circuit and determine the impedance looking into the terminals.

The terminals A ...
